Teach pendants are widely used in on-site industrial control systems, such as industrial robots, automatic dispensers, spot welders, robotic arms, etc., to realize information prompting and human-machine dialogue with the mechanical body. Lavichip provides a full set of robot handheld teach pendant solutions, which can be based on Linux/VGA/HMI/androids platforms, effectively shortening the R&D cycle, simplifying the software design process, enabling rapid development and application of the customer's needs, and helping the customer's products to the market as soon as possible.

Generally speaking, for industrial robots or industrial equipment teaching method has the following ways:
1, direct teaching method: ① power level off teaching, ② servo level on teaching;
2, the remote control teaching method: ① teach pendant teaching, ② lever teaching, ③ master-slave teaching;
3, indirect teaching method: ① simulated robot teaching, ② special tools teaching;
4, remote control teaching method: ① numerical input teaching, ② graphic teaching, ③ software language teaching.


Direct teaching based on position control：
Drag teaching relies on the external robot's multidimensional operation sensors, through the sensor feedback position information, to pull the robot end in Cartesian space to do linear or rotary motion. However, this type of teaching has both advantages and disadvantages compared to direct teaching with handheld teach pendants. Due to the need for additional sensors to provide information feedback, this will directly increase the application cost of the robot, and it is also unable to control the single-axis motion of the robot arm well, and the movement will be very stiff, which is not conducive to industrial production.


Direct teaching based on torque control：
This direct teaching method, relying on modeling algorithms, the controller can be calculated in real time when the robot running drag moment, generate records and instructions. Unlike traditional position- or impedance-based drag teaching methods, the zero-force control method is much more operator-friendly. With the help of an accurate dynamics model, the gravity, friction, and inertia forces that the robot has to overcome when being dragged are offset by the corresponding motor moments, allowing the robot to be dragged with ease. At the same time, the algorithm also ensures that when the external force is withdrawn, the robot can quickly come to a standstill in its current position, ensuring the safety of the equipment and the operator.


Remote Control Based Teachers：
Lavichip Robot Teach pendants with industrial robot body using human-machine interaction terminals, using high-definition display touch and large-size screen, with three-level industrial EMC, IP65 dustproof and waterproof grade. Based on many years of experience, the programming interface and software are completely independent of independent development, secondary programming, really should be the customer needs. Compared with other ways of teaching, the way of teaching programming is really “ultra-simple” operation. Personnel with certain basic knowledge of electrical appliances can start the application in a very short time.
